create_recording_canvas expects as a last parameter a render node, which is used to reuse deallocated display lists. Passing the render node improved performance in several tests and it is matching how HWUI is using that API too. bug: 69131471 Test: tvappGlTex DrawFrame is 1ms faster Change-Id: I93d8da694c178d3fb8d1aa52afa76dd8271e93cb
